Lomifylline is an inducer that induces the release of Ca2+ stored in cells, specifically through the ryanodine receptor.

Cyclic ADP-ribose ammonium (cADPR ammonium) is a powerful calcium mobilization second messenger synthesized from NAD+ by an ADP-ribosyl cyclase. It primarily raises cytosolic calcium levels through Ryanodine receptor-mediated release from the endoplasmic reticulum, while also facilitating extracellular influx through the opening of TRPM2 channels [1][2][3].

JTV-519 fumarate (K201 fumarate) 是 一种 SERCA 阻断剂和兰尼碱受体的部分激动剂，具有抗心律失常和心脏保护作用，可改善肌浆网钙渗漏，可用于研究焦虑症。

Paraxanthine (1,7-dimethylxanthine) 是一种 caffeine 的代谢物，能够刺激Ryanodine 受体通道来抑制多巴胺能细胞的死亡。

Azumolene sodium dihydrate is a muscle relaxant that inhibits the release of calcium from skeletal muscle sarcoplasmic reticulum. Azumolene inhibits a component of store-operated calcium entry coupled to the skeletal muscle ryanodine receptor.

Azumolene sodium anhydrous is a muscle relaxant that inhibits the release of calcium from skeletal muscle sarcoplasmic reticulum. Azumolene inhibits a component of store-operated calcium entry coupled to the skeletal muscle ryanodine receptor. Azumolene, an equipotent dantrolene analog, inhibits a component of SOCE coupled to activation of RyR1 by caffeine and ryanodine, whereas the SOCE component induced by thapsigargin is not affected.

RyRs activator 3 (compound A4) 作为有效杀虫剂，针对斑小菜蛾 (M. separata) 及小菜蛾 (P. xylostella) 显示出较高效力，其对斑小菜蛾的 LC50 值达到 3.27 mg L。通过与兰尼碱受体 (ryanodine receptor) 结合，RyRs activator 3 能增加细胞质中 Ca2+ 的浓度，从而产生生物毒性。

Maurocalcine是一种能穿透细胞膜的激动剂，对ryanodine receptor (RyR)通道1、2、3型具有活性。在与RyR1的结合实验中，Maurocalcine诱导[3H]ryanodine的结合，表现出EC50值为2558 nM。此外，Maurocalcine对RyR2也展示出较高的表观亲和力，达14 nM。该化合物可用于体内细胞追踪及其他细胞成像技术。

RyRs activator 4为一款昆虫兰尼碱受体激活剂，对粘虫幼虫显示出显著的杀灭活性，其半致死浓度(LC50)为1.32 mg L。

ent-(+)-verticilide is an effective and specific inhibitor of cardiac ryanodine receptor (RyR2) calcium release channels, demonstrating antiarrhythmic properties. It suppresses RyR2-mediated diastolic Ca2+ leak and shows greater potency and a unique action mechanism compared to Dantrolene and Tetracaine. ent-(+)-verticilide serves as a valuable tool for exploring the therapeutic potential of addressing RyR2 hyperactivity in cardiac and neurological conditions [1].
